19 Claims.

This invention relates to closures for containers.

It has been found that with ordinary closures, purchasers of variousproducts, particularly liquors, cannot be sure that they are getting thelegitimate product for the reason that the contents of the bottle orother container are often tampered with between the packaging source andthe consumer. Various ways of preventing this illicit tampering havebeen attempted but, for one reason or another, they have not provedentirely satisfactory.

It is an object of the present invention to provide simple and effectivemeans for closing bottles and other containers such that the contentscannot be tampered with, at least without the fact of such tamperingbeing made evident.

It is a further object of the invention to provide closure means forcontainers such that the container is initially hermetically sealed,such seal being readily and quickly broken when it is desired to use thecontents.

It is a still further object of the invention to provide a closure forcontainers having improved means for sealing a once opened containeragainst leakage.

With these and other objects in View, the invention consists in thefeatures, combinations, details of construction and arrangements ofparts which will first be described in connection with the accompanyingdrawings and then more particularly pointed out.

Referring to the drawings, and more particularly to Figs. 1-6, there isprovided a container and an initially imperforate end closure forinitially completely closing and sealing the mouth of the container,this end closure having a frangible portion which is subsequentlypunctured to permit discharge of the container contents.

As here shown as an example, a container, such as a bottle 2 i, has aneck 22 provided with a thread 23. At the mouth of the bottle is theusual locking ring 24, such as is commonly provided for securing crowncorks and other well known closures.

While the initial end closure and its frangible portion may vary inconstruction and arrangement, in the present 'exemplification it is partof an attachment which also performs other functions hereinafterreferred to. To this end, the attachment comprises a ring-like bodyportion 25 surrounding the mouth of the bottle. Extending inwardly frombody portion 25 is a clamping flange ZS-overlapping the lip of thebottle. To prevent leakage between the bottle and the attachment agasket 2? of cork or other suitable material may be interposed betweenflange 23 and the bottle lip. From the flange 26, the wall of theattachment has an upstanding portion 28. Inside the latter is arelatively hori zontal frangible annulus 29 and inside that is a conicalplug or valve element 30 hereinafter referred to. Below body portion 25is an inwardly extending bend 3| which takes under the shoulder of thebottle locking ring 2t. It will now be apparent that this bend and theclamping flange 25 serve to secure the attachment to the bottle. In thepresent exemplification, the bend 3| is formed by spinning the metal ofthe attachment in under the locking ring shoulder.

In carrying out the invention to what is now considered the bestadvantage, the frangible portion of the initial end closure is arrangedto be disrupted over a predetermined area. This may be accomplished, forexample, by weakening the wall of the end closure in such a manner thata given area of metal is broken away. In the exemplification illustratedin Figs. 1-6 the attachment which comprises the end closure is formed ofso-called sheet metal and the weakening is conveniently accomplished byscoring the annulus 29 to define the area or areas to be broken away.

\ To this end, and as shown more clearly in Figs.

1 and 5, the annulus 29 has four weakened portions. Each area 33 to bebroken away is defined by an end scoring 34 and two side scorings 35,36. There is no scoring at the remaining end in order that the metalwill be disrupted in the form of tongues which remain rooted to theannulus, whereby no metal is allowed to drop into the container.

The invention in its entirety includes a cap for the container, axiallymovable on the container neck, and means for causing the frangibleportion of the end closure to be broken away upon the initial movementof the cap into full closed posi tion. Although capable of variousconstructions,

in that illustrated as an example in Figs. 1-6,

a cup-shaped cap 31 telescopes the bottle mouth and has an internalthread 38 engaging the bottle thread 23. This cap may conveniently beformed of molded plastic material. Extending downwardly from the top ofthe cap are one or more puncturing elements or breakers 39, the. numberdepending upon the number of areas in the end closure that are to bebroken away. In the present instance there are four such areas and fourbreakers.

With reference to the direction of rotation of the cap in approachingclosed position, the leading face of each breaker 39 is slightly roundedand is V-shaped at the bottom to provide a piercing or breaking point.As appears more clearly in Fig. 6, each breaker recedes, toward thetrailing end, to a vanishing point, to enable the cap to be removed fromthe manufacturing mold.

The invention in its entirety includes means for initially assemblingthe attachment in a predetermined angular position and for subsequentlypreventing relative angular movement of the attachment, thereby toinsure the breakers and the weakened areas of the diaphragm having theproper relative position. While this may be accomplished in variousways, in the embodiment here shown as an example, the locking ring 24has a vertical groove 42 and the body portion 25 of the attachment has astruck-in nib 43 which takes into the groove 42 (Fig. 4). I

With this construction, the attachment may be initially assembled in apredetermined angular position on the bottle mouth and is thereafterlocked in such position. In this way, the breakers are properlypositioned with respect to the weakened areas. In the presentembodiment, as will be more apparent hereinafter, it is desired that thepuncturing operation end with the cap in full closed position.Consequently, the attachment is given such a position that when the capis sufficiently short of full closed position to enable the puncturingoperation to be completed during final movement, the advance points ofthe breakers are just about to engage the end scorings of the weakenedareas.

After the bottle has been filled and the initial end closure attached,the cap is assembled but is screwed down only part way toward fullclosed existence of this unbroken end closure prevents tampering withthe contents.

When it is desired to use the contents, the cap is screwed down to fullclosed position. During this combined rotary and axial movement of thecap, the leading ends of the puncturing elements 39 are forced againstweakenedareas 33- and cause the same to be broken away along the scoredlines. The displaced metal rolls or curls up ahead of the breakers inthe form of tongues which remain rooted integrally to the annulus 29(Fig. 2). This piercing or breaking away results in the formation of aplurality of ports or passages 44 through which the bottle contents maythereafter flow (Fig. 3).

The invention in its entirety includes a cap having a discharge port anda valve element carried by the container neck for closing said port inone position of the cap. As here shown as an example, centrally locatedin the top of the cap 31 is a conical discharge port or passage 45 (Fig.3). When the cap is screwed down to closed position this port is ciosedand sealed by the conical valve element or plug 35 above referred to(Fig. 2).

The invention in its entirety includes means for indicating to apurchaser or user whether or not the cap has been given thepredetermined movement necessary to puncture the initial end closure.This may conveniently be accomplished by means operable upon saidpredetermined movement for altering the external appearance of the cap.Although capable of Various constructions, in the embodiment illustratedas an example in Figs. 1 5, the cap discharge port 45 is initiallyclosed by an integral web 46 which may conveniently be the moldersflash. This web, at the top, is flush with the top of the cap so as topresent a neat appearance. In order to insure an easy break-out of theweb, its wall is made as thin as practicable around the edge thereof, asappears at 41 (Fig. 1).

In this particular embodiment the valve element or plug 30 is utilizedto break out the web. As previously described, the initial end closureis punctured when the cap is first screwed down to closed position. Ithas also been stated that in closed position of the cap, discharge port45 is closed by plug 30. It will be apparent, therefore, that thepredetermined movement of the cap' that causes the end closure to bepunctured also causes the web 46 to be broken out, thus altering theexternal appearance of the cap and indicating that the puncturingmovement has taken place. Fig. 2 illustrates the parts at the end ofthis initial closing movement of the cap with web 45 just broken out.With the construction described, the web breaks out with a clean outleaving a. completed discharge port. It will be understood that the webdrops away and is discarded. I

The invention in its entirety includes means for preventing completeremoval of the cap and such means will advantageously be inaccessible.Although capable of various constructions, the locking means here shownas an example comprises a downwardly and outwardly extending lockingflange 50.

part of the attachment previously described. As appears in the drawings(Figs. 1-5), the attachment has a V-shaped bend taking under theshoulder of the bottle locking ring 24, the lower leg of the Vconstituting the locking flange 50. Cooperating with this flange is abead 5| formed on the inner wall of the cap, above the thread, and in aposition to be below flange 50 when the This flange is of flexible andresilient material, e. g. metal, and is formed as cap is assembled onthe container. This bead provides an upwardly facing shoulder the innerdiameter of which is slightly less than the normal diameter of the rimof flange 50. Above head is a recess 52 to accommodate the flange 59during opening and closing movements of the cap.

In the initial assembly of the cap onto the bottle neck, the threadcrests and the bead 5| ratchet over the edge of flange 50 which yieldsor flexes inwardly. Once the bead 5| has passed, the flange springs backto approximately its initial position. Thereafter, it serves as a look--ing abutment, cooperating with bead 5| to prevent removal of the cap.That is, upon a given upward movement of the cap, bead 5| engages therim of flange 50, as appears in Fig. 3, whereby further movement isprevented. If desired, flange 5-9 may be split to facilitate itsflexibility.

In carrying out the invention in its entirety, provision is made forsealing the container mouth in closed position of the cap, once thepackage has been opened, this sealing being designed to prevent leakagenot only through the discharge port but also down through the thread.This may be accomplished, in connection with plug 30, by effecting aseal outside the ultimate passages in the initial end closure. Althoughcapable of various constructions, in the exemplification of Figs. 1-6the cap is provided with a shoulder 53. Secured to this shoulder in anysuitable manner is a sealing gasket 54 of cork or other suitablematerial. When the cap is in closed position (Fig. 2), the dischargeport 45 is closed and sealed by plug 30 and gasket 54 is compressedagainst clamping flange 26 to prevent leakage down the thread.

To review the operation: after the bottle is filled the attachmentcomprising the initial end closure is assembled on the bottle mouth, theproper angular position being determined by the engagement of nib 43 ingroove 42 (Fig. 4). Then the skirt of the attachment is spun in underthe bottle locking ring 24 and the end of the skirt is flared outwardlyto form the locking flange 50. Finally, the cap 31 is assembled on thecontainer, the bead 5| and thread crests ratcheting over the edge offlange 50. The cap and bottle threads are caused to inter-engage but thecap is screwed down only part way towards full closed position, beingstopped before the breakers 39 engage the frangible portion of the endclosure. The package remains in this condition until the user desires todischarge the contents.

With the construction described, the package is tamper-proof in thesense that no tampering is possible without the fact of such tamperingbeing made evident. Since the same movement that breaks the initial endclosure also breaks away web 46, the purchaser or user can tell at aglance whether or not the package is in its original condition. That is,if the top of the cap presents an unbroken surface, the purchaser knowsthat the contents are still sealed by the initial end closure and thatthere can have been no tampering. If, on the other hand, the cap has aport in its top face, the purchaser knows that the cap must have been somoved as to break the initial closure and he is thereby put on noticethat there may have been tampering. With the construction described,moreover, the above mentioned indication cannot be avoided by removingthe cap, puncturing or removing the initial closure, and replacing thecap with web 46 intact because the cap is locked against removal. Andfinally, since thelocking means is inaccessible, the lock cannot betampered with without destroying the skirt of the cap and so making itevident that something is wrong.

When the user wishes to open the package, he screws the cap down to fullclosed position (Fig. 2), thus puncturing the initial closure andbreaking out web 45 (Fig. 2). Then he screws the cap back to openposition (Fig. 3), in which position the bottle contents can flow outthrough openings 44 and port 45. To re-seal the package, cap 37 is againscrewed down to closed position. In that position, plug 30 closes port45 and sealing gasket 54 prevents leakage down the thread.

In the construction shown in Figs. 1-6 a right hand thread for the capis provided. It will be understood that for a left hand thread, thedirection of facing of the breakers 39 and the weakened areas 33 will bereversed.

In Figs. 7-11 there is illustrated a modification. The main differencesare that the attachment is in two parts instead of one and that there isa difierent method of subsequent sealing. In this additional embodiment,a container 55 has a neck provided with a thread 51 like the threadpreviously described. Telescoping the bottle neck is a cup-shaped,internally threaded cap 58 formed of molded plastic material. In the topof the cap is a conical discharge port 59 initially closed by anintegral web 60 like the web previously described. In closed position ofthe cap the port 59 is closed by a conical valve element or plug 6|.

In packaging various liquids and other products it is considerednecessary, or at least preferable, to avoid contact of the contents withaluminum, tin plate or other so-called sheet metals. The objections tosuch contact do not apply, however, to other materials such, forexample, as pure tin (using the term to mean commercially pure tin, asdistinguished from tin plate, but not necessarily chemically pure tin).To make the complete attachment, such as that shown in Figs. 1-6, ofpure tin involves too great an expense and, in addition, pure tin isprobably not suitable for the clamping and locking features of theattachment.

According to the present exemplification, there is provided a two-partattachment so constituted 1 that the part which comes into contact withthe container contents may be formed of one material and the part whichis secured to the container of another material. These parts may,

for convenience, be referred to as the closure part and the anchoringpart.

As here shown as an example, the closure part (Fig. 9) comprises aring-like body portion 65 and terminates at the bottom in an outwardflange 65. Inside the body portion is a relatively flat frangibleannulus 6'! and the plug 6|. This part of the two-part attachment, whichcomes in contact with the bottle contents, may be made of tin, e. g.what is known as extruded tin.

The anchoring part of the attachment, which does not come in contactwith the bottle contents, may be made of any suitable sheet metal or thelike. As shown (Fig. it comprises a ring-like body portion 68 at the topof which is an inward clamping flange 69 which overlaps the flange 65 toanchor the end closure when the parts are assembled. Below the bodyportion 68 is an inward V-shaped bend 10, the lower leg of the Vconstituting an outwardly and downwardly flaring locking flange ll.

ing ring'l3.

' 'tThe exemplification of a two-part attachment illustrated in Figs.7-10 may be constructed to be assembled with a snap-on action. To thisend, the v-shaped bend H3 and the. locking flange ll, which correspondto the ultimate bend and flange :of Figsxl -S, are pre-formed. Theanchoring part .ofthe attachment is split, as at 12, at a number "ofpoints around its circumference, these splits extending from the bottomedge'of the locking flange through the V-shaped bend and Well up intothe body portion 68 (Fig. Cooperating with the split attachment, thebottle hasa lock- The lip of the bottle, which forms the top of thelocking ring, is sloping or rounded,

as'appears in Figs. 7 and 8, for reasons hereinafter referred to.

To enable the anchoring part of the attach- -ment to be assembled in apredetermined angular position, the body portion 53 has an inward nib Mwhich takes into a groove, like groove 42, in the locking ring of thebottle. This engagement also serves to prevent any relative angularmovement after assembly. To enable the closure part of the attachment tobe assembled and retained ina predetermined angular position, theclamping flange '69 has two notches which receive lugslt formed on theclosure portion.

To assemble the two-part attachment above described, the two parts arefirst brought together into the relation of Figs. 7 and 8, the splitV-shaped bend iii yielding to pass flange 66. Thereafter the attachmentas a unit is assembled onto the bottle mouth. As the unit is applied tothe bottle, the pressure of the V-shaped bend against the lip of thebottle causes the split skirt In this position, overlapped flanges 66,69, are

pulled down against the bottle'mouth, or against a sealing gasket i? ifone is used, and the twopart attachment is secured, as a unit, to thebottle neck.

It is to be understood that the two-piece attachment may be secured inplace by a spinning action instead of by the snap-on action justdescribed. In that case, the anchoring portion is not pre-formed as tobend I6 and locking flange H and the splits 12 may be omitted. The twoparts may be assembled together as above described, and then applied tothe container as a unit, the skirt of the anchoring portion being spunin under the bottle locking rim and flared outwardly to form lockingflange 'H. Similarly, the one-piece attachment of Figs. 1-5 may beadapted to a snap-on assembly by pre-forming and splitting the skirt.

The cap 53 has an internal bead 18, like the bead 5!, which provides anupwardly facing shoulder for engaging the locking flange H to preventremoval of the cap. The cap also has a recess 19 like recess 52. It willbe apparent'that cap 58 is assembled in the same manner as cap 31.

In connection with Figs. 1-6, there was described the feature ofeffecting a seal, for a once opened container, outside the openings inthe initial end closure. In the modification of Figs. 7-11 this scalingis accomplished by forcing or wedging a part carried by the containerneck against a part of the cap when the cap is in full I w: ima ines lport .clos'ed'position. This further embodiment also has,:means forpuncturing or breaking predeter- -mined areas of the initial end closureand the wedging. and breaking elements may conveniently be combined.

"In the exemplification illustrated in Figs. 7-9, V

annulus 6'5 is surrounded by an outer wall 8| which is conveniently arim or lip formed as a continuation of ring 65. The annulus B1is'provided with a plurality, in this instance four, weakened areas 83formed conveniently by a thinning of the metal, as appears in Figs. '7and 9.

Extending downwardly from the top of the cap and alined with annulus 61is an annular wedge .84. At intervals corresponding to the number ofweakened areas 83, this wedge is extended into a plurality of puncturingelements or breakers 85 generally like the breakers previouslydescribed. :Surrounding this wedge and spaced therefrom sufficiently toreceive lip 8|, the cap has a vertical abutment wall 82.

ment, the breakers 85 puncture the weakened areas 83. While the drawingsillustrate the metal as being broken away over the weakened areas. .andcurled up ahead of the breakers, it' is to be understood that this doesnot necessarily result from'the construction described. It is possiblethat in some cases the weakened area will be split or ruptured andpushed aside.

puncturing provides passages in the end closure for the flow of thecontainer contents. During .the'end' of this same movement of the cap,web :lii! is broken out by plug 6|. screwed up to open position again,thus opening Then the cap "is port 59 to permit discharge of thecontents.

To reclose the container, the cap is again screwed down to full closedposition. 'In this position plug 6| closes port 59 and the breakersentercand at least partially close the openings previously formed. Thewedge 84 engages lip 8| and by its wedging action forces the lipoutwardly against abutment wall 82 of the cap. This wedging action, bytaking up the clearance between the cap and the attachment, due tomanufacturing tolernaces, effects a tight seal around the entireperiphery of the closure outside the end passages.

In Fig. 12 is illustrated a further modification.

In this embodiment certain features of the invention are shown inconnection with a collapsible tube such as is used for pastes, creamsand the like.

As shown as an example, a collapsible tube 88 has a threaded neck 89.Formed as an integral part of the neck is an initially imperforate end'wall 95 having a plurality of weakened areas 9|,

in this instance three. These weakened areas are thinned portions of anannulus bounded by an outer wall 94 which is conveniently formed as aterminal lip on the container neck. Rising from.

In any event, the? this end wall and integral therewith is a conicalplug or valve element 92.-

In threaded relation with the tube neck is a a cup-shaped cap I02 havinga conical discharge No web for initially closing this port isillustrated'but'one may be used if desired. The cap has an annular wedge95 extended at intervals to form breakers 96. Surrounding the wedge,

-and'spaced therefrom sufficiently to receive lip '94, is a verticalabutment wall 98. When the cap is first screwed down to full closedposition the breakers break away the weakened areas 9|, as previouslydescribed in connection with Figs. 7-11, to form passages for the flowof the tube contents. After the cap has been opened and again closed,the breakers enter the passages to close the same and the wedge forceslip 94 against abutment wall 98, taking up the clearance, to efiect aseal. Carried by the tube neck is a locking flange like those previouslydescribed. To this end, as here shown as an example, a short distancebelow the mouth of the container is an external bead 99 which may betermed a locking ring since it is analogous, for this purpose, to thelocking ring 13 of Figs. 7 and 8. Secured to this locking ring by asnap-on action is an attachment generally like the lower or anchoringpart of the attachment shown in Figs. 7, 8 and 10 and terminating inlooking flange I00. Cooperating with this flange, to prevent removal ofthe cap, is a bead Illl on the cap similar to the beads previouslydescribed. The cap has a gasket I04 corresponding to gasket 54 of Figs.1-3.

In the exemplifications here shown and described, the locking flangesand complementary anchoring portions of theattachments are annular. Itwill be understood, however, that the invention is not limited to thatform and that the desired result may be obtained by one or moresegmental locking and anchoring elements.

In the various embodiments here illustrated, the caps and containerthreads are mutually engaged at all times, once the cap is assembled onthe container. It is to be understood, however, that,

if desired, the parts may be so arranged that the cap thread disengagesthecontainer thread before the internal bead of the cap engages thelocking flange on the container. With such an arrangement the threadsare not in engagement when the cap is in its uppermost or full openposition and out of contact with the top of the initial closure element.

The invention has been described in connection with bottles andcollapsible tubes but it is to be understood that the invention isapplicable to various kinds and types of containers.
